-To fli/v u'hmn, it 11mg/ concern:

Be it known that l, CHARLES H. MELvIN, a citizen oi' the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improxf'enients in Disk Gang-Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Hy invention is designed especially with reference to disk gang-plows, but is also applicable to plows of other types, and hence not imited to the particular embodiment herein illustrated and described.

The principall objects of the invention are,

Iirst, to provide a simple and efficient adjustable frame for gang-plows which while supporting the disks or other furrow-turning devices in proper receding order and in suitable relationA to the furrow-wheels and line of draft will permit ready adjustment or change of the relative positions of the disks or furrowopeners for regulating the width of furrow or furrows turned between them, this adjustment being accomplished without the aid of separate spreading devices or similar contrivances; second, to render the construction adaptable for readyT conversion from a gangplow into a single plow, or vvice versa, simpIy y omitting or adding one or more parts of the frame and disk or disks supported thereby without altering the position or relation of the remaining disk or disks; third, to provide improved means for adjustment or shifting of the position of the front furrow-wheel for` the purpose of regulating the width of furrow cut by the front disk or furrow-opener, also for lateral adjustment of the draft devices, so as to equalize the draft, and for .adjustment of the` land-wheel, so as to regulate the tread in accordance with the work to be done; fourth, to provide improved means for automatically turning or castering the front furrow-wheel by the-draft or pull, also for setting said furrow-wheel at any desired angle to the draft; fifth, to provide a latch device for controlling the rear caster-wheel; sixth, to provide imroved means for raising and lowering the wheels with their caster-spindles, so las to shift said spindles by parallel motion ;.sev-l enth, to produce improved bearin s for the disks and also for the wheels of tgfie implel ment, and, finally, to simplify theconstruction and, arrangement of parts and yto iinprove generally upon limplements ofy this same character.

from the field, this view being taken from the landside of the implement.

Fi 13 is a cross-section through one` of the W eel-hubs. Fig. 14 is aplan view of a plow-frame of modiied construction, and Fig. 15 is a section taken on line XV XV of Fig. 14.

My improved gang-plow frame consists, essentially, of two or more beams orframe memscale, showin the implement cons" standard and bearing, respectively. Fig. 94

bers adjustably secured lengthwise together or'fone. to another in receding order and arto the line of draft. Each ranged diagonally Hh fr o e ame of said adjustable beams or parts l supports one of the disks or other furrowbent arm or angular extension, to which the A disk-bearing or plow-standard is attached,

the said bearing or standard being thus bolted in such position as not to interferef with the range of adj ustability of the several members of the frame. Referring to the implement illustrated in Figs. 1, 2, and 5, the plow-frame consists of two of such adjustable beams or parts, which are designated by the letters A A. To their rearward-bent arms or angular extensions are bolted or otherwise secured the standards B, which support the furrow-openers ordisks C. Said arms are parallel and also diagonally disposed, so that the disks, which are supported orl mounted substantially parallel with the arms, are held in proper relation and with their cutting edges disposed at a suitable angle or oblique to the line of draft.

vThe beamsare preferably substantially- 'shaped' in cross-section, as shown in Fig. 3,

vand their vforward main arms or members are provided with corresponding series of boltholes'a, arranged, preferably, at equal distances apart, whereby the beams may. be. bolted lengthwisetogether indifferent positions, so as to support the disks at different distancesv apart, and thus regulate the width of furrgw turned by the rear disk. It will be observed alsov that adjustment of the beams changes th'e relative position' of the disks both laterally and longitudinally of the line of draft, so that -for a narrow furrow the rear disk stands closer behind the front disk, while for a wider'furrow said rear disk is moved farther behind said front disk, thus always maintaining a sufficient recedence in order to prevent any crowding of the furrow between therdisks. In the construction referred to the'said adjustable frame is supported by a land-wheel D, a front furrow-wheel E, and a rearcaster-wheel F, which are mounted on crank axles or spindles d, `e, and f, respectively. The implement is also .provided with a drivers .seat G, the seat-spring g of which may be secured to the 'frame in any suitable manner, and is further provided with a tongue or tongue-plate H and a suitable clevis. 71 atv the front end thereof.A This tongue-plaie'is diagonally flanged at its rear 'end and belted to the rear Side of the front beam or frame member'. By unfastenin'g the bolts the tongue-plate may be slid along the beam and secured thereto in different positions, thus adjusting the lateral position of the hitch or draft devices-a feature which is especially advantageous in connection with f the capacity of the frame for adjustment of f. the disks.

The inner end or spindle ofthe land-wheel crank-axle d is journal'ed in a tubular bearing d', which is formed integrally with a bracket or plate d2, having flanges or lugs embracing the outer side'of the rear beam A and secured l theretobythe same bolts which fasten the two beams /t/ogether. The -bracket may', however, be secured to the beam by separate bolts yor other means and may also be secured to said beam in different positions, so as to regulate thel tread of the land-wheel to correspond with the work to be done. The crank-axle d may be rocked in its bearing to adjust the height ofthe land-wheel by means of a lever J, rigidly secured to said crankaxle, said lever being provided with the usual locking and unlocking device orl handpiece and connected spring-actuated bolt engaging the teeth of a segmental rack j, which latter is bolted to the other end of the spindle-` l This casting has also a horizontal bearing, in

which is journaled one end or spindle of a crank e3. The other end or spindle of said crank is journaled in a bearing or casting e4, secured to orbetween the outer bent ends of straps e5, which are bolted to the front beam or member of the lbw-frame. Pivoted'to the casting e? is av ifting-lever K, having a short arm 7c, which is parallel with crank e3 and is'fulcrumed or pivoted at e to an upstanding arm e7 on the bearing e4. The crank e3 and arm 7c thus constitute parallelmotion links, wherebyfwhen the furrowwheelis raised or lowered by the lever K the spindlere is moved parallel with itself and always maintained in the lsame verticalrela'- tion to' the frame. The lever K is also provided with the usual vlocking and unlocking devicevor handpiece and connected springroo actuated bolt engaging a segmental rack kf,

which latter is rigidly secured to or formed integrally with the casting e2. Y

The straps e5, which hold the castingy e,

.with the furrow-wheel and other parts supported thereby, are provided with a number of bolt-holesv corresponding with the boltholes in the beams A, so as to permit adjustment of saidstrapson the front beam to change the lateral position of the front furrow-wheel, and thus regulate the widthof furrow cut bythe front'disk. Usuallythe bolt-holes in the compound frame or beams and in the straps are Aso arranger? that the IIO gang-plow may be adjusted to turn furrows` either eight, ten,or twelve inches in width.

The angle of inclination of the front furrow-wheel with the line of draft-is controlled by the draft-elevis by means of .a link L, .the

front end offwhich is coupled with the clevis Vor cle'vis-bolt, while its'rearportion is connected with the spindle e bya suitable connecting device, soithat when theplowis at work the wheel is yheld in line; but whenthe implement is turned either to the right or left l the furrow-wheel is also turned properly around in the same direction. The connect-l ing device between the link and spindle infthe comprises a yoke or stirrup casting Z, which' straddles the upper part of the spindle and is construction illustrated (see Figs. and 11) pivotally secured thereto, and a loop or sleeve casting Z', through which the link is slidably fitted, said loop-casting being rigidly secured to the free end of the stirrup-casting by a single fastening-bolt. The loop-casting is thus permitted to swing Vfreely in a vertical-direction, so that raising and lowering of the fur# row-wheel will not cause the link to bind in. any way. bration ofthe loopfcasting up or down will not be communicated to the Wheel, becausethe link slides freely through its loops and holds the .wheel in proper line. The construction of the two'castings is such that the fastening-nut may be loosened and the loopcasting turned to give the furrow-wheel any desired set with relation to the line of draft, and the nut may then be tightened again to secure said castings rigidly together, so that this set will remain constant during the operation of the implement. The parts described thus `constitute an independent leading device for the front furrow-wheel.

The inner vertical end or spindle of the rear caster-wheel crank-axle f is journaled in a bearing or casting f havingl a front vertical rib f Figs. 1 and 2,' slidably secured in acorresponding slot or groove in a casting M, which is bolted or rigidly secured to the rear beam or frame member. The seat-spring g, as shown, is also attached to said casting M.

The castings M and f are connected at each side by a pair of'parallel links n, pivotally secured at opposite ends lto said castings, the upper link at one side being an angular arm of a lifting or operating lever N. Said lever is also provided with the usual handpiece and connected spring-actuated bolt engaging a segmental rack n', which-is bolted to a suitableprojection]r3 at the top ofthe bearing or casting f. By these means said vertical spindleof the crank-axle f is always moved parallel to itself. per or lower position the casting f is held tightly against its .companion casting M .by the links/n, thus making a rigid connection.

A latch O is pivoted tothe rear of the castingf and engages the crank-axle f, and said latch is so constructed as to 'permit free cas-A tering of the rear wheel in one direction, but to preventcastering in the opposite direction.' It is also provided with a trip device or treadle o, adapted to be Worked b foot ofthe driver to raise the latch, an thus permit castering in either. direction. Thus in a right-hand plow, as illustrated in the present case, when the implement is turned haw," or-to the left, the rear-Wheel casters ra-utomaticallyto make the turn; but when the implement is turned "gee, or to the right, the wheel can caster onlyT by pressing the treadle to raise the latch. If the latch is It will be noted, also, that any vi-v n either its extreme upthe released by the foot when the wheel comes to its regular position, the latch automatically locks the crank-axle in position, preventing castering except in the one direction. [n the case of a left-hand plow the arrangement would of course be reversed, the wheel being permitted to caster for a gec" turn, but prevented from castering on a haw turn. Downward movement of the latch may be properly limited by its abutment against the casting or by stops or other suitable means It is a parent that the rear beam or framebar of t e implement may be unbolted'and removed, and the castings d and M, which support the land-wheel and rear caster wheel and seat, may then be bolted or secured to the front beam, thus converting the implement into a single plow, such as represented in Fig. 4. By replacing thc said rea beam and disk carried thereby Athe implement may be reconverted into a double plow. The plow-frame may be formed of any suitable number of said beams or adjustable parts adapted to support a corresponding number of disks or furrow-openers, the beams being adjustably secured lengthwise one to another in successive order to maintain the disks or furrow-opening devices in proper receding relation. Tnus'by adding a third beam adjustable on the second the implement may be converted into a triple plo\v. In the case of a multiple-disk plow the casting M, which supports the rear caster-wheel and seat, would be moved back and secured to the rear member of the frame, and the bracket d', which supports the land-wheel, would also be moved back and secured to the last beam of the series, thus always preserving the proper relations of the various parts.

Each Wheel of the implement herein shown `consists of a main-wheel casting and supplementary outer and inner hub-castings P and p, which are bolted to the central portion of the Wheel at opposite sides and constitute the entire bearings of the Wheel on the axle or spindle. (See Fig. A13.) Within the ccntral opening or hub portion of the Wheelcastin is loosely fitted a collar p, secured in IOO lace a s rin h'cotter orl other suitable P Y P g .means, said collar serving to hold the Wheel in roper place on the spindle. The outer hug-casting P has an outer closed end or tubular bearing portion, and this, together with the central chamber or opening in the Wheel proper, forms a dust-proof oil-socket,

"which when supplied with oil permits the Wheel-spindle to be constantly lubricated. To insure further against entrance of dust to the bearings, a dust cap or band p2 is secured on the Wheel-spindle, so as to overlap the inner tubular end of the inner hub-casting p, this device of course being secured in place before the hub-castings, wheel, and collar are ut on the spindle.

, T ie disks illustrated are secured by countersunk bolts to star-shaped concave castings Q, the heads of the bolts being flush with the front surfaces of the disks to render the latter perfectly smooth. Said castings Q are formed at the back with centrallybored spindles g with surrounding annular recesses q', formingball-races. The standards B, which support the disks, are formed with tubular bearings l), which fit .1o over the spindles q 'and within the annular recesses q, suitable'balls vor antifriction devices being interposed, if desired. An oiltube b may be inserted into the bearin b to keep the spindle lubricated, Asaid tubes 1(hein i 5 closed by a suitable cap b2. Each casting is secured toits bearing B by means of a single connecting-bolt, which passes through the spindle q and is fastened in place by anut and washer, as shown in Fig. 9. The head of this bolt fits into a socket in the face of the casting Q entirely behind the disk. This construction dispenses'with the usual central bolts inserted through" the' disks, leaving their faces entirelysmooth and offering nov 2 5 obstruction to the 'free passage of earth.

The disks may be provided with scrapers S, the Shanks s of which are secured to the upper horizontal members of flat angle-barsr L-shaped standards R. Said-horizontal Amembers project over the upperledges of the disks from the vertical members of said standards, which are bolted to the diskstandards B. Theshank of each scraper is secured-by a suitable clip to the vertical leg 3 5 orface of a small angle-plate r, as shown .more clearly in Fig. 12, the clip which holds the shank being perferably corrugated on its inner surface to prevent the shank from turning". The horizontal leg ofsaid angle-plate 4o rests on top of the bar R, and said angle-plate is supplemented under ythe bar by a similarly-disposedangle-plate r. The horizontal legs or members of said angle-plates are' connected by a vertical bolt, Iand a horizontal bolt passing through both of their vertical members and through the corrugated clip serves to clamp the shank and at the same time to clamp the angle-plates to the bar R.

The shank may of course'be supported by other means, if desired. It will be luiderstood that the adjustable frame and disks or furrow-turning devices may be dierently mounted or supported or the plow-Wheels differently arran ed, if desired,`and that the invention is capa le of embodiment in diHerent constructions and is applicable to imple.- ments of vother types or with other furrowturningl devices than those herein illustrated.

One modification of the invention is illustrated in Figs. 14-and 15, where the letters A A designate'thebearns or frame-bars gonsisting of L-shapedor angle beams lavr their forward main varms or members Afitted one within the other and bolted together. lIn 6 5 this"'censtri'ictioliF the ful'r'owand land wheels .are connected to the angled beam vided with corresponding series of bolt-holes suitable castings, retaining the adju sjtmenT and capacity for operationpossessedvgby the:

corresponding parts when the b eam' me`n` bers are made 'of the ordinary rail or vI'crdssf- 7'6 section type:
